1 Application filed'March 25, 1912. Serial No. 686,027.

' To all whom it may concern:

. Be it known that I, WILLIAM S. HAMM, a citizen of the UnitedStates, and resident of Hubbard Woods, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Window-Sashes and Weather-Guards Therefor, of which the following is a specification, and which are illustrated in the accom anying drawings, forming a part thereof The invention relates to window sash and Weather guards therefor, being especially adapted for use in connection wlth car windows; its objectbeing'to provide a simple, inexpensive and .eiiicient guard for excluding drafts, dust and moisture atthe side edges of the sash.

In the accompanying drawings illiistrat-' ing the invention- Figure 1 is a detail plan' section of a window casing, a pair of sashes and theweather guard; Fig. 2 is a sectional detail in perspective of the side rail of the sash; Fig. 3 is a sectional detail inperspective of the weather guard; and Fig. 4. is a sectional detail in perspective of the retaining strip'for the weather guard.

The mvention may be used in connection with any form of window casing, there being shown a casing 10 having an adjustable stile plate 11, an inner sash strip:l 12, and an intermediate sash stop 13. ere is shown in thedrawings an inner sash 14 and an outer sash '15, the side rails 16, 117, thereof being of wood, their width being such that they do not enter the runways between the casing stops. These side rails are longitudinally moved, as shown at 18, and to, the outer ace of each the weather guard is applied.

This weather guard ,indicated as a whole by the numeral 19, is formed of a sheet of spring metal, the central portion of which conforms to the outer edge of the sash, being provided with a rib 20 for entering the groove 18. The plate extends outwardly beyond each face of the sash rail, its marginal ortions being bent inwardly so as to ive t eplate, broadly speaking, a U shape. lhe side 'arms ofthe U, designated by the numorals 21, 22, normally incline outwardly with reference to the plane of the adjacent side face of the sash rail. Preferably each of the wings thus formed is united with the transverse portion of the plate by an outwardly bowed section 23, 24, for increasing tures, as 28, in the weather its resiliency and covering the edge of the stop with. which it cooperates.

A retaining strip 25 is applied to the edge of the sash rail, fitting against the transverse member of the weather guard and being provided with a longitudinal rib 26 for entering the rib 20 thereof. The strip 25 is securedto the sash by any suitable means, such as screws 27, which pass through suitable aperguard. The strip 25 is preferably of less width than the thickness of the rail 16, thereby leaving a space between each of its side faces and the adjacent stop, within which the wings 21, 22, of the weather guard are located. I

When the sash is in place the win s of the weather guard bearoutwardly an with a spring pressure against the stops, and thus effectually exclude air currents, dust and moisture while leaving the sash free to slide within the ways. Preferably the strip 25 is of such thickness that it'is in sliding engagement with the face of the stile plate 11, so as to prevent rattling of the sash, while the length of the wings 21, 22, is such that they do not make contact with the stile plate.

1. In a window sash and Weather guard therefor, in combination, aside rail, a retaining strip securedto the edge of the rail, and adapted to engage the stile face of a casing a spring metal plate located at theside of'and spaced apart from the strip and having a flange clamped between the strip and the sash rail. I

2. In a window sashand weather guard therefor, in combination, a side rail, a U- shaped plate of spring metal fitted to the edge of the rail, its marginal portions projecting outwardly from the rail and being inclined away each from the other, and a retaining strip for clamping the plate to the rail and projecting beyond the edges of the marginal portions of the plate.

3. In'a window sash and weather guard therefor, in combination, a side rail having a longitudinal channel in its outer edge, a spring metal plate fitted to the edge of the While the weather guard is shown as rail and having a rib entering its channel, the marginal portions being folded to the planes of the side faces ofth'e rail but inclined outwardly from such lanes, and a retaining strip of less width t. an the thickness of the rail and secured to the edge thereof over the metal plate and projecting beyond the edges of the marginal portions of the plate.

4.'In a window sash. and weather guard therefor, in combination, a side rail having a longitudinal channel in its outer edge, a spring metal plate fitted to the edge of the rail and having a rib entering its channel,

of the rail and secured to the edge thereof over the metal plate and having a longitudinal rib entering the rib of the plate such 7 strip extending beyond the edges of the marthe plate.
